COMBINED WATER-HEATER AND WASHING -MACHlNE.

EPEGIFICATION forming part of Letters Patent N 0. 718,778, dated January 20, 1903.

Application filed September 20, 1901. Serial No. 75.678- (No model.)

To aZZ'whom it may concern:

Be it known that I, BENNETT LUNGREN, a citizen of the United States, residing at Alexandria, in the county of Douglas, State of Minnesota, have invented certain new and useful Improvements in a Combined Water- Heater and Washing-Machine and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to washing-machines; and it has for its object to combine therewith an attachment that may be used for heating water in the body of the machine and which may be operated either with wood or with gasolene as fuel, a further object of the invention being to provide a construction wherein the parts may be easily and quickly adjusted interchangeably.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation showing a washing machine equipped in accordance with the present invention. Fig. 2 is a perspective view showing the fire-box with the gasolene-burner removed and the smoke-pipe in place. Fig. 3 is a vertical section through the fire-box and showing the gasolene-burner in place.

Referring now to the drawings, there is shown a washing-machine having a metallic water-holding body 5, in which the water is to be heated and in which the fabrics are to be washed and which body is supported upon legs 6. The under side of the body in the present instance is convex, and fitted thereagainst is a metallic fire-box, including the bottom grate 7, the sides 8 and 9, and the ends 10 and 11, the box being rectangular in plan, while the sides are concaved to fit against the under side of the body 5, the box being held against the under side of the body by means of bolts engaged in slotted ears 14, projecting laterally from the upper edges of the box and on which bolts are engaged nuts 15, which when screwed up hold'the fire-box close up against the bottom of the body of the washing-machine; In one end 10 of the fire-box is a door-opening 16, provided with a closure 17, while at the opposite end 11 is a smoke-opening 18, from which projects outwardly a flange 19 to receive a smoke-pipe, a cap 20 being provided for coveringthe opening by engaging over the flange when the smokepipe is removed and the gasolene-burner is used. This cap is connected to the box by a chain 211 to prevent loss when inactive. The fire-box when the smoke-pipe is in place is adapted to receive wood or other fuel upon its grateto be burned to heat water placed in the body 5 of the washing-machine.

When gasolene is to be used for heating the water in the body 5, a burner apparatus is used, comprising a tank 30, from which leads a fuel-pipe 31, first downwardly, then laterally, as shown at 32, and then upwardly at 33, where it terminates in a burner 34, the flow of gasolene from the tank to the burner being regulated by the valve 35, located near to the tank. At the lower end of the vertical portion 33 of the fuel-pipe is a depending bracket 35, having an enlarged base, as shown, and in which is an axial threaded perforation to receive the screw 36, having an enlarged head 37 in the form of a hand-wheel, as shown. When the burner apparatus is to be used, the laterally-projecting portion is passed inwardly of the fire-box through the fire-door thereof, and the bracket is disposed to rest upon the grate, the screw being then passed upwardly between the bars of the grate and engaged with the threaded perforation of the bracket, when by rotating the hand-wheel it will be brought to impinge tightly against the under side of the grate to hold the burner apparatus in place.

In practice modifications of the specific construction shown may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention, it being further understood that when the burner is used the cap is placed over the smoke-hole of the box, and the door is opened or may be taken off.

What is claimed is- A portable furnace comprising a box having a grated bottom and having a door in one of its sides, a fuel-pipe passing through the door in a horizontal plane and turning upwardly at its ends, the outer endconnecting with a supply-tank and the inner end with a burner, a centrallyperforated support depending from the supply-pipe and resting In testimony whereof I affix my signature upon a number of the grate-bars, the perfoin presence of two Witnesses.
